RATE-FINDER.

To all whom it may] concern,"

Be it known that I, FREDERICK. J. BAUR, acitizen of the United States, residing in- Lucas county. Ohio, have inventednew and s useful Rate-Finders, of which the followis a specification.

his nvention has utility in connection,

with the ready determination of the relation of quantities, and as disclosed," has a'fur- 1-0 ther feature of automatic check asto the quantities taken.

This invention may be conveniently embodied as a rate finder, as in parcel post,

is a view similar toFig. 1, with parts broken away, and with the movable members shifted to give a rate determination. The base or mounting plate 1 may be attached to a Wall or other support by the screws 2, which screws 2 may serve with the rivets 3 to carry in assembled relation to x the plate 1, theouter housing late This,

outei housing-plate 4 has the sight, openings 3. or shits 5, 6, for rate total indications. The

back or mounting-plate 1 has the stop 7 for determining the recover limit of movement or travel of the movable members disposed between the honsing plates.

Connecting the housingplates 1, 4, is the central bearing or pin Sloosely mounted on which is the dish: 9. By the pin 12, spring 13 is connectedto the back housing plate 1,

while the pin 14- connects this spiral spring 13 to the disk 9, thereby serving normally to keep this disk member 9 with-itsextension 10 abutting the stop 7 of the plate 1. The extension 10 has a set of quantity graduations, in this instance pounds, with finger 5 openings 11 to permit ready definite acthation of the member 9 upon its axis bearing 8 against the resistance ofthe spring-13. This member 9 has thereon in a common line the weight and rate totals for such Weight in each of the postal zones. As the Y member 9 is rotative, aconvenient disposal of these gradnations or quantity indications 15 is diametrically.

' Spaced from the member 9 and coaxialtherewith is the second movable member 16,

which also has the central bearing 8. The disk member 16 has openings If? therethrough to expose certain, Weight and zone totals of'the quantities 15. on the member The member 16 is also provided with an; 30

extension 18 spaced froinl the: extension 16 of the member 9, to permit ready insertion .7 of the fingers of the operator in" the indice Y tions 19'for ready definite zone determina: tions. .Engaging'the member liiis thepin idtl to site vend of which spring 21 is connected I the .'-pin 22 to the front housing Ipliite Accordingly this springfiil normally keeps, thezone member 16 in first or. local rate place against the stop 7 on the'plate has is the member 9 kept in one pound positidn' against the same stop ,7. 1

At the right hand limit of the slot or sight opening 6, the member 16 discloses at 76 indication 23, the check of weight quantity shifted in the movement of the member 9, while the indications 24- along' the remaining extent of the openings 5, 6, disclose the zone quantity or designation shifted by the so member 16, this check being atthe point of rate total display. There is accordingly a double automatic check of each of the elements entering into the total, all displayed 7 at a single glance, and obtained by most simple manipulation. lVith one hand, one

- finger'mayhe inserted into an opening 11 for poundsa second finger inserted into an opening 19, even during; movement of the hand, as the skilled operator pulls both disk members until the fingers come against the lower stop 25. This stop 25 gives a definite. limit, and the display is of numbers well vcentered for easy reading. Upon release of].

the mechanism by Withdrawing thefingers; the springs 13 and 22,":1t once effect a re covery of the members 9, 16, and with no" delay the rate finder is'available for the next operation. r l

The simplicity of the mechanism and the accuracy and clearness of determinations contribute to tlm efiiciency and reliability of the device in practice.

What is claimed and it is desired to secure by Letters Patent is:,

1. The combination in a. computing device of a support,. a pair of'relatively movable v members each provided vvith indicating means and a plurality of independently selectable starting-position finger engaging 1 b ndicutions, a housing provided by the support; heyigg' an epenin disclosing the from; member Opening and itsre ism-y with the (then-member xfesuitant in mum, and-e aid-fin erab tmept limitigg the actuating of b ;T hei 'sffb'y'j "erig ngrin'g the epeietors .fin'gt'rs hnoviilg the memher's'; thereby dis aclfhdt'tofiijf the hieliibei's' 'irdiirsmi'ting p'o theifmember having resultant disclosing memes pamllei' oiz e in frofit of the hhr, the front .memher having openings therethrough, the
